COBCH1128 No STOP RUN, GOBACK, or EXIT PROGRAM statements encountered in source
The source has no STOP RUN, GOBACK or EXIT PROGRAM statement. Your COBOL system automatically inserts an EXIT statement followed by a STOP RUN statement following the last line in the program. However, this might not have the effect you desire.
COBCH1131 Statement generated no executable code
This error might be produced when, for example, an INITIALIZE statement does not cause any code to be created. It is an indication that the statement can be removed from the program. If the error is ignored the effect is as if the statement were removed.
